Abstract

In order to evaluate some of agronomic traits correlated with quality in some bread wheat cultivars,we use agronomic traits and protein markers,in this way an experiment was designated at Researcher farm of Pars-Abad of Moghan Juniorcollege of Agriculture using 29 Spring and Facultative bread wheat genotypes based on randomized complete block design with 3 repetitions in 2010. Agronomic traits consist of biological yield( Kg.h-1), number of plant ( m2), number of tiller ( m2), plant height ( cm), spike length ( cm), number of spike ( m2), number of spikel in spike, number of grain in spike, 1000 grain weight (gr), grain yield ( kg.m2), single plant yield ( gr), harvest index, flag leaf area ( cm2), flag leaf chlorophyll scale, emergencing time, tillering time, estem elongation time, booting time, flowering time, milking time, doughing time and complete ripening grain time measurement and was recoreded. The results showed significant differ of traits biological yield, grain yield, harvest index, plant no, number of tiller, number of grain in spike, 100 grain weight, grain yield, single plant yield and flag leaf chlorophyll and tillering time between genotypes. Between morphological traits, Biological yield, had positive and significant correlation with grain yield. The phenologic between most traits was observed positive and significant relationships. Shiroodi, Nick-Nejad and Alborz cultivars for traits grain yield, biological yield, harvest index and one plant yield were cultivars paramount whereas, Bayat, Toos and Roshan cultivars for said traits were sector cultivars with low means. The results of regression coefficients showed the good relation between some characters and proteins band and could be represented that some of coding loci of storage proteins are involved in regulation mechanisms of studied characters and so, storage proteins could be used as biochemical markers in assessment of quality in bread wheat.
